How much does a will cost in Illinois is one of the first questions people ask when they finally sit down to plan ahead. The good news is that a basic will is one of the most affordable legal documents you can make. In most cases, the price depends on how you make it and how complex your wishes are. A simple do-it-yourself will can cost almost nothing. A will drafted by an attorney usually costs a few hundred dollars. This guide breaks down the real numbers so you can choose what fits your family and your budget without guessing.
What Goes Into the Cost of an Illinois Will
The price of a will comes down to three things: the method, the complexity, and whether you need extra documents. A single-page will leaving everything to one person is simple. A will with trusts, business assets, or blended-family wishes takes more work. As a result, the more careful planning you need, the more you typically pay.
Illinois law keeps the basic rules simple, which helps keep costs down. Under 755 ILCS 5/4-3, your will must be in writing, signed by you, and signed by two witnesses. Each witness must sign in your presence. You do not need a notary to make the will valid. However, adding a notarized “self-proving affidavit” can save your family a court step later.
Because the legal bar is straightforward, many families can make a valid will for very little. For example, the biggest cost is often just the time to think through who gets what and who will serve as your executor (the person who carries out your wishes).
How Much Does a Will Cost in Illinois by Method
So, how much does a will cost in Illinois in real dollars? It depends heavily on the route you take. Below is a plain-English breakdown of typical price ranges. These are general market figures, not fixed legal fees, so your quote may differ.
| Method | Typical Cost | Best For |
|---|---|---|
| Free template or state form | $0 – $50 | Very simple wishes, one main beneficiary |
| Online will service | $100 – $250 | Modest estates, some guided steps |
| Attorney-drafted simple will | $300 – $1,000 | Most families wanting peace of mind |
| Full estate plan (will, trust, powers of attorney) | $1,500 – $4,000+ | Larger estates, blended families, business owners |
For example, a healthy single person leaving everything to one child might spend $0 to $100. However, a married couple with a home, kids, and retirement accounts often chooses an attorney. When people ask how much does a will cost in Illinois for a typical middle-class family, the honest answer is usually $300 to $1,000 for an attorney-drafted will.
Keep in mind that a will alone does not cover everything. Many attorneys bundle a will with a power of attorney for healthcare and finances. That is why full-plan pricing is higher.
What You Save Later Also Matters
When you weigh how much does a will cost in Illinois, look at the money it can save your family down the road. A clear will can help your loved ones avoid confusion, delay, and extra court costs. Dying without a will is called dying “intestate.” When that happens, Illinois law decides who inherits, not you.
Illinois also offers a shortcut for smaller estates. Under 755 ILCS 5/25-1, families can use a small estate affidavit when the personal property is worth $150,000 or less. This limit rose from $100,000 on August 15, 2025 under Public Act 104-0346. Registered vehicles no longer count toward that figure. This tool can help many families skip formal probate entirely.
Estate tax is a separate issue and affects very few people. Illinois taxes estates worth more than $4 million. The federal exemption is much higher at $15 million for 2026. So most families never owe estate tax at all. A will does not change these thresholds, but good planning can help larger estates prepare.
How to Get Your Will Done Without Overpaying
Start by listing what you own and who you want to receive it. Next, decide who will be your executor and, if you have young children, who will be their guardian. These choices cost nothing and make every method faster.

If your wishes are simple, a reputable online service or state form may be enough. However, if you own a home, have a blended family, or run a business, talk to a licensed Illinois attorney. Ask for a flat fee up front so there are no surprises. Typically, attorneys will quote a set price for a simple will.
Finally, sign correctly. Use two witnesses, and consider a notarized self-proving affidavit. You may be able to handle much of this yourself, but check with your state’s court self-help resources or a licensed attorney if anything feels unclear.
Frequently Asked Questions
Do I need a lawyer to make a valid will in Illinois?
No, Illinois does not require a lawyer. Your will is valid if it is written, signed by you, and signed by two witnesses. However, an attorney can help if your situation is complex.
Is a handwritten will legal in Illinois?
A handwritten will can be valid, but only if it meets the witness rules. Illinois generally does not recognize unwitnessed handwritten wills. For that reason, always use two witnesses to be safe.
Does a will avoid probate in Illinois?
Not by itself. However, small estates with $150,000 or less in personal property may skip formal probate using a small estate affidavit. Larger estates often use a living trust to avoid probate.
Make Sure Your Plan Actually Works
A will or trust only does its job if the rest of your plan lines up. Two quick checks before you finish:
- Get your state’s exact rules — witnesses, notary, probate cost, and tax thresholds vary by state.
- Beneficiary forms beat your will — make sure your life-insurance beneficiaries are current, because named beneficiaries pass outside your will.
